Y., assignor to'Joseph l\Ndil;er and Samuel, Miller, both of New York,

y t 1 Claim. This invention comprises a fire resistant portfolio, large wallet, portable document file, or the like. i

In its preferred form, the invention comprises a folded portfolio or wallet having tight pockets Whose walls include a lining of asbestos material. This asbestos lining directly contacts'the docu to the ends of the pocket openings. The outer 3 surfaces of the asbestos lining may be covered by a smooth layer of attractive material, such as leatherette, or chemically treated paper.

The following is a more detailed description of the invention, in conjunction with a drawing, wherein:

. Fig. 1 illustrates a, perspective view of a portfolioor wallet, in closed position, in accordance with the invention; I

.Fig. 2 is an open View of the same portfolio or wallet; t

Fig. 3 shows a face view of the portfolio or wallet completely opened and broken away in certain parts to illustrate the construction more clearly;

Figs. 4 and 5 illustrate the development of the portfolio or wallet in the process of manufacture,

and particularly show how theasbestos lining is put together to form the pockets;

piece "of asbestos shown arbitrarily divided. by dotted lines into parts 1 and 8. These dotted lines form the folds for the article; In Fig. 5,

, the end portions 8, shown in Fig. 4, have been fitting walls.

folded over the inner portions I and stapled at theouter edges to form two pockets with closely Although Figs. 4 and 5 show how the pockets vmay be made from a single piece of asbestos, it should be understood that, if desired, the inner and outer walls of thepockets may be made from separate pieces of asbestos lining stapled together at their outer edges. One such arrangement is shown in Fig. 8.

In manufacturing the complete article, the asbestos lining is covered with a suitable attractive coating material 9 which is stitched. to all of the edges of the portfolioor wallet, as shown. This coating 9 may be leatherette, or a chemically treatedpaper material, or any othendesired coating material. The sections 2 and 3 of the completed article may thus be semi-rigid in characwhen the article is the unattractive asbestos lining from being seen open. This is shown in Figs.

3 and 6. t

Because of the fire resistant character of the asbestos lining l, 8, the portfolio cannot be completely consumed by fire, and will protect any.

documents held between thewalls of the pockets,

even though the outer covering 9 is burned. The

metal staples 5 prevent the pocketwalls from separating, and thus are a bar to fire entering the pockets. I i

What is claimed is:

A document folder comprising two sections on opposite sides of aifoldable center line, each section having a pocket whose confronting surfaces are composed of sheetings of closely fitting aslbestos material, metallic staples securing together theside edges of said asbestos sheetings,

the pockets may more readily be understood from i an inspection of Figs. 4 and 5 which are develop:

ments in the process of manufacturing the portfolio or wallet. Fig. 4 shows the first stepin the process of manufacture and illustrates a single said pockets having slit-like openings adjacent said center line, a coveringfor said asbestos materi-al independently stitched to the edges of said pockets and covering said staples, and a narrow strip of said covering extending between .said openings along the center line of said folder and having its edges extend at most for only a short distance within said pockets to conceal the asbestos when the folder is opened, whereby the contents to fir'e even while the covering and stitches are consumed by said the.
